An organic electroluminescence device including an organic layer including at least a light-emitting layer between a pair of electrodes, wherein a light-emitting plane of the organic electroluminescence device comprises at least two light-emitting areas having light emission colors that are different from each other, of which one is a first light-emitting area emitting a light of a first color and another is a second light-emitting area emitting a light of a second color, wherein the second light-emitting area has a composition that is the same as that of the first light-emitting area and is denatured to the second light-emitting area by heating. An organic electroluminescence device and a producing method thereof having excellent production feasibility are provided.
An organic electroluminescence device comprising an organic layer including at least a light-emitting layer between a pair of electrodes, wherein a light-emitting plane of the organic electroluminescence device comprises at least two light-emitting areas having light emission colors that are different from each other, of which one is a first light-emitting area emitting a light of a first color and another is a second light-emitting area emitting a light of a second color, wherein the second light-emitting area has a composition that is the same as that of the first light-emitting area and is denatured to the second light-emitting area by heating.
A producing method for an organic electroluminescence device comprising at least two light-emitting areas in a light-emitting plane having different wavelengths of light emission, wherein the producing method comprises forming a laminate member, in which a first electrode, an organic layer including at least a light-emitting layer, and a second electrode are laminated on a substrate, and then carrying out denaturing by locally heating at a temperature higher than a glass transition temperature of a host material of the light-emitting layer, to thereby form either one of the light-emitting areas.
